OT: 1U server preferences?

[Karsten Bolding <karsten@bolding-burchard.com>]

Hello

I'm in the process of investigating 1U servers and have sofar received
offers for:

IBM: x335
Dell: PowerEdge 1750 
SuperMicro: SuperServer 6013A-T

all with dual 2.8GHz Xeon 2x80GB disks (SCSI or SATA).

>From a pure price point of view the SuperMicro machine is preferreble
and compared to the others it also have hot-swapable bays. Is there
any reason why I should not go for this solution? 

Another thing. /proc/cpuinfo and memory amount is identical on two 
different machines (HP and IBM) but the performance differs by 35% 
for a pure CPU-limited program. The IMB machine has Chipkill - can that
explain the performance difference? Both machines are dual Xeon 2.8 GHz
machines.
The program has been run several times and all timings shows the same.
